I’ve been serching everywhere I can think of, to find “Underwater” Contour maps of Reservoir’s in my state of Maryland. But I can’t find any. Could you please help me out! My grandson ask me and I can’t give him a true answer, where the dropoffs are, or how deep it is here. I don’t have the money to get expensive Sonar/fish finding equipment for a boat that cost 60.00 per day to rent. We would like to some day help our wounded solgiers get out on the water and enjoy the life that they so galently fought for.

Navionics has a PC app that you can purchase off of their website and download on your computer. It’s the same information that you would get on their Hot Maps chip that you would put in a sonar unit. But the cool thing about this is you can view it on a much larger monitor get an idea of where you want to go before you hit the water. I have found that it’s not 100% accurate, but it’s pretty close. You can order it in regions, just like the chip. I would definitely recommend looking into this. This might be what your looking for.

Good advice, and a great addition to help prepare for your next fishing trip. Also, the waypoints, trails, routes…..ect are all transferrable to your unit via SD card.
